Help me!

Ma

I’m 7 weeks PP I’ve had sex 3 times all 3 times we’ve used protection we started last Monday... can’t believe I’m even asking this but could I be pregnant and showing symptoms already?? We don’t want another baby right now obviously if I was pregnant then I guess it was meant to happen but I feel nauseous at night and during the day I feel just crappy... please tell me that it’s too soon for symptoms😭 last time I found out I was pregnant I didn’t have any symptoms yet
